In the scope of an extraordinary maintenance, the Municipality of Trieste awarded FPC ITALIA the inspection and the check of the tension of the stays of the Bruno Bianchi swimming pool roof located in Trieste.
No. 8 stays of which four are made up of 35 strands and four are made up of 20 strands (unbonded strands) have been checked.
The position of the anchoring heads, at an altitude of 8 meters above the pool and accessible only with aerial platforms, required a special kind of work using only small size light equipment.
In the first phase of the work, we checked the load of each stay by verifying the tension of each individual strand. The results obtained showed an almost homogeneous distribution of forces except for some strands in which the tensions were slightly different from the expected load, always remaining below the safety range foreseen for the capacity of the type of strand used.
At the end of the check, the FPC ITALIA technical office analyzed the data collected and, in agreement with the designer, it was decided to proceed with a calibration of all the stays by adjusting the force of the only strands that presented a different tension than expected, not in line with the rest of the strands.
The whole inspection was carried out by a team of six FPC ITALIA technicians, with specific equipment owned by FPC ITALIA.
The work was successfully carried out in eight days and with great satisfaction of the customer for the prompt reaction, the professionalism and the precision in very short time.
